Application med February 29, 1916. Serial No. 91,085.

To all whom tt may concern: Be it known that I, CHARLES Mnnvinrai UPHAM,of Stoughton, in the county o1 Nor-4 tolk, and in the State ofMassachusetts, have invented a certain new and useful llmprovement in.Water-Supplying Apparatus, and do hereby declare that the following isa full, clear, and exact description thereor.

ll/lly invention relates particularly to an apparatus designed forsupplying water in regulated quantities, and more especially to concretemixers, although it has general application in the supplying, of liquidsof any desired character forany desired purpose.

Hitherto devices for supplying\ water to concrete mixers have beenprovided with a tiltable pipeto act as the intake and outlet for thewater from the supply tank pro-- vided for supplying water to theconcrete miner, the said pipe being arranged so that been found inapparatus of this character',y

however, that when the pipe is acting as an outlet, as `the waterapproaches the lowest level from which it can be drained by the outletpipe, there is a continual decrease in the dow of the water, untiltoward the end when the last quantity of water is being drained ed",there is a long continued eX- tremely small flow of water through theoutlet pipe. This is due largely to the shape and position ofthe tiltedend of the pipe, acting as an outlet forthe water. This provides a veryunsatisfactory means for supplyin water particularly in concrete mixersw ere it is desired to provide quickly a measured quantity of water.Furthermore, where there is at the end of the operation ol draw 0H thewater a long continued How of water in small amounts, it usually happensthat the out-flow is cut oli' during this long continued liow .atvarying times, thus rendering the amount of water supplied indeiinite. i

The object of my invention is toprovide an apparatus, by means of whicha definite uantity of water may be supplied for any esired purpose,butespecially in concrete miners, andA so that the long continued flowof water in small quantities toward vthe end of the operation of drawing0H the water trom the supply receptacle may be obviated.

While my invention is capable of embodian adjustable pipe 13 angplarposition,

v pipe 13 is connected ment in many did'erent forms, for the pur pose ofillustration 1 have shown only one form of lnvention in the accompanyingdrawings, 1n which,

Figure 1 is a longitudinal vertical section of an apparatus made inaccordance with my invention; and A Fig. 2 is a horizontal section ofthe same taken' on line 2/2of Fig. 1.

In the drawings I have shown a supply tank 1 having a cylindrical bodyportion 2, and outwardly curved ends 3, which are connected together byrivets 4 inthe usual way. An air inlet and outlet valve 5 is provided-4at the top of the tank 1, said valve '5 also serving to indicate whenthe tank 1 is filled with water. To the bottom of the tank there isconnected a casing 6 by means of rivets 7. A. pipe 8 enters the casing 6at one side thereof, said pipe 8 communicating with a'three-way valve 9,which controls the supply to said pipe 8 of water from a pipe 10, andthe discharge of the water through the pipe 8 into a pipe 11. Thethree-way valve 9 is constructed so as to thus convey water into thetank through the pipe 8 from the pipe 10, or discharge the same throughthe pipe 8 and pipe 11, or to be moved into neutral position so astoprevent the liow of water into the pipe 8. AThe casing 6 communicateswith an opening 12 in the bottom of the tank 1, so as to permit thepassage of into the tank, the lower end of which pipe 13 is pivotallysupported in the bottom of the housing', in such a manner as tocommunicate with the pipe 8. This pipe 13, has at its lower end,furthermore, a lever arm 14 which projects through the housing 6, andwhich is adapted to be moved by a handle 15 into any desired theposition of the lever eing shown by a scale 16 on a segment or a circle17 which depends from the outside of the housing 6. The upper end of theby right angle pipe couplings 18 and 19 to an intake and outlet nozzle20 having a downwardly directed horizontalopening 21, the said couplingsbeing rotatably connected. This nozzle 20 carbeing provided for thepassage of the link 23 :lol

from the tank l into the housing 25. It will be noted that the pivot 24is the same distance from the pivoted end of the rod 22, as the lowerpivot of the pipe 13 is from the upper pivotal connection of said pipewith the nozzle 20, and that the distance of the upper pivoted end ofthe link 23 :from the upper pivotal connection of the pipe 13 is thesame as theI distance of the lower pivotal connection of said pipe 13from the pivot 24. It will also be noted that the lower pivotalconnectionof the pipe 13 and the pivot 241@l are on the same level.

In the operation of my invention, when it 1t desired to convey ameasured quantity of Water from the pipe l1 to any suitable apparatus,as for example, a concrete mixer, the valve 9 is turned so as to admitwater from vthe pipe 10 through the pipe 8 and the pipe 13 and thenozzle 20 into the tank 1. When the tank l is completely filled, thiswill be indicated by the fact that the water has reached the top of theair valve 5. The valve 9 is then turned so as to cut oi the water fromthe pipe 8. The handle 15 is then moved to the desired position alongthe scale 16, indicating the quantity of water desired to be supplied bythe apparatus. The movement of the handle 15 lowers or elevates thenozzle 20 so as to control theI quantity of water to be discharged fromthe tank 1. uch movement of the handle 15 to adjust the elevation of thenozzle 20, however, does not in any Way disturb the in-- clination ofthe opening 21, but the position of the opening 21, because of thepresence of the link 23, remains substantially horizontal. The three-wayvalve" 9 is now turned so as to permit the discharge 'of water from thetank 1 through the nozzle 20, the pipe 13, Owing to the fact that theopenlng 21 is in a horizontal position, however, the desired quantity ofwater will be rapidly drawn off and the supply of water in this mannerwill quickly cease, as soon as it has reached the low level of theopening 21, as the pipe 13 and nozzle 20 can thereafter no longeroperate to draw oil the water located below the opening 21. From this itWill be seen that the elevation of the nozzle v20 and the opening 2l maybe adjusted, as desired, so as to draw but at all times said nozzle 20maintains its horizontal position, so as to bring about a rapid iow ofWater while being discharged from the tank 1, and a sudden and completetermination of the iiow of the water when tllie pre-determined quantityhas been supp 1e While I have described my invention above in detail, Iwish it to be understood that many changes may be made therein the pipe8, and the pipe 11. l

pif the desired quantity of water,`

without departing from the spirit of my invention.

I claim 1. In combination, drawing of 'varying from the same, comprisingan adjustable nozzle having an opening adapted to maintain substantiallyconstant angular position, a pipe pivotally connected to one end of thenozzle, and a link connected to the other end of the nozzle.

2. In combination, a tank and means for drawing of varying quantities ofliquid from the same, comprising an adjustable nozzle having an openingadapted to maintain substantially constant angular position, and a linkconnected to one end of the nozzle.

3.

4. In combination, a tank and means for vdrawing ofi?` varyingquantities of liquid from the same, comprising an adjustable nozzlehavingan opening adapted to maintain substantially constant angularposition, a pipe pivotally connected to one end of the nozzle, a linkconnected to the other end of the nozzle, and an adjusting handleconnected to said pipe.

5. A tank having a horizontal discharge nozzle, a parallel movementmechanism connected to the same, and means for regulating the positionof such mechanism.

6. In combination, a tank, a horizontal nozzle therein, a dischargepipe, and a link pivoted to said tank, said discharge pipe and said linkbeing also pivotally connected to said nozzle, and means for movingangularly said discharge pipe.
